Thanks Alexandre with your informations, very useful. I intend to do 
something like that but unfortunately I didn't find any good 
router/firewall appliance in my budget to do that on the administration 

Do you know if it's possible to force Proxmox Web built-in to listen on 
localhost only ? Thus I could build an Apache2 with mod_security as a 
reverse proxy for WAN access.
